My daughter had her 3 year checkup today. She is 43 inches(3'7") and 44 pounds, perfectly proportionate! The size of an average 5 year old. She is right on track developmentally, and the doctor said personality wise, she's even a little advanced! So proud of my big kid!

She was born via c section and she was strictly formula fed. So you see, it doesn't really matter how they come into this world, or whether you breast feed or formula feed. As long as you keep them healthy and safe!
